Strain rate dependency of materials
The mechanical response of materials can be affected by how fast the loads are applied, how quick deformation occurs. For instance, polymers tend to be stronger at higher speeds of deformation than at quasi-static regime due to their viscoelastic nature. In my research, I investigate how different materials behave at quasi-static and at dynamic regimes. This information is later translated into mechanical models to help engineers to design real components.
Ageing of composite materials
My research is oriented to the study of composite materials for underwater and aerospace applications. During service conditions these composites will be subjected to humid environments. My current investigation aims to develop a constitutive model able to capture the effects of water uptake upon the strain rate dependent properties of composites. Previously, in my master thesis, I investigated the degradation of fracture toughness of an epoxy resin due to hygrothermal aging.
Development of novel experimental techniques
I like to be challenged by complex experimental setups. I have designed and built bespoke equipment (thermal chambers for in-situ testing) and experimental setups for micromechanical tests (micro compresion, tension and compact tension rigs).
Compression performance of composites
Fibre composites have an unveiled potential in compression. Improvements in their matrix, fibres, interfaces and architecture can prevent or delay instabilities causing failure in compression.
